VEHICLE-BRAKE.

SPECIFICATION forming part -of Letters Patent No. 375,397, datedDecember 27, 1887.

Application filed August 26, 1887. Serial No. 247,968. (No model.)

To all whom it may concern:

Be it known that 1, JAMES K. P. TIMMoNs, a citizen of the United States,residing at Timmons, in the county of Murray and State of Tennessee,have invented a new and useful Improvement in Vehicle-Brakes, of whichthe following is a specification.

This invention has reference to brakes for vehicles, and it consists inthe improvements hereinafter described, whereby the general constructionof the brake is simplified and its efficiency of operation increased.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View of a single tongue and adjacent parts having myimprovements combined therewith. Fig. 2 is a perspective view showingthe application of the improved brake to a construction where a pair ofshafts are used.

Fig. 3 shows the lever arrangement for applying the brake. Fig. 4 is adetail view of the retaining-hook of slightly-different construction.

By referring to Fig. 1, it will be seen that the tongue A carries theusual doubletree arrangement, B, back of which extends the diverginghounds a b. A transverse bar, 0, is secured on the hounds, and has itsend portions, 0, extending at either side of said hounds, and to each ofwhich is pivoted the central portion of a bent brake-lever, D, the innerportion, (1, of which extends substantially parallel with the barO,While its outer portion, 6, is curved and carries at its extremityabrakeshoe, f. A curved link, E, is pivotally connected at its ends tothe inner ends of the brake-levers.

The front axle, F, carries at its upper side the king-bolt g, and thisking-bolt g is embraced bythe curved portions h upon an arm, i, whichextends horizontally from the said bolt, the rear portion of said armbeing bifurcated to embrace said bolt, as stated, and then terminatingin downwardly-curved members T T,which are secured at the rear of theaxle.

The arm i is provided with a vertical .perforation, in which is hung avertical member, k, of a catch device, the said member having its lowerend extending a short distance below the arm 1', and carrying a nut, Z,at said end. The member 76 has a hook, m, which extends out integrallyfrom said member. A coiled springis interposed between said hook and armt and tends to hold the hook down under the arm. Now, when said link Eis moved rearwardly, the brake-levers will be operated to throw theirshoes away from the wheels, and can be held in such disengaging positionby rotating the member is in its bearing to cause the hook to take overand engage the link. For positively releasing said brake-levers I haveprovided the construction shown in Fig. 2, wherein the clip a, uponwhich the king-bolt is mounted, carries at its lower side a plate, G,which has a part, 0, depending below the axle, and then extendsouthorizontally, where it is bifurcated, as shown. The bifurcated portionis perforated transversely for the passage of a bolt, 1), upon which ismounted the lower end of a handlever, H. This lever is designed to bearagainst the foot of the curved link to move so as to operate thebrake-levers.

From the foregoing it will be readily seen that the devices are simple,easily applied, and can be readily applied to existing vehicles Withoutany difficulty.

The lever arrangement for applying the brake is that shown in Figs. 1and 3, wherein two metallic plates, 8 s, are secured on the tongue orforward portion of the hounds, so as to form a bracket, in which ispivoted a lever, S. The plates are inclined in opposite directions, soas to form braces. Upon the cross-bar G is located a pulley, t. A ropeor chain, a, is connected to-the link E, and passes around said pulleyt, and is connected to the lower end of the lever.- This arrangementpermits the lever to be moved to its limit in one direction, so that itsposition will bind it to retain the lever and hold the brakes againstthe wheels. The extreme movement of the lever in the opposite directionwill also hold the lever and serve to maintain the brakes in adisengaged position.

I claim 1. The combination, in a vehicle-brake, of the tongue or shafts,the brake-levers e, the link connecting the inner ends of said levers,means to operate the levers, and the springdepressed Vertically-movableswinging hook to engage the link, substantially as described.

In a vehicle-brake, the combination of the tongue or shafts and theirhounds, of pivoted hrakelevers, a link pivotally connecting I levers,front axle having king-bolt and ahoritheir inner ends, means foroperating said link, zontal arm extending therefrom, and a springand acatch for retaining said link, substanactuated hook bearing in said arm,substantially as described. tially as described.
